The DUCIS SD-401/402 Series Bottom Dead Center Monitor (Computerized Slug Detector) is an advanced die protection device, specialized for detecting slugs or other unusual obstructions in progressive dies.

The device operates by installing a sensor on the lower die holder and a "proximity element" on the stripper plate. By continuously measuring the distance between these two parts at the bottom dead center (BDC) with an accuracy of 1µm (0.001mm), the device can detect any minor changes. If a slug gets stuck, the stripper plate cannot return to its standard BDC position, and the device will immediately send a signal to stop the machine.
✨Key Features of the SD-40x Series
1. High Accuracy (1µm)
The device allows setting the monitoring tolerance in micrometers (from ±1µm to ±99µm), enabling the detection of the smallest changes.
2. High Speed (1200 S.P.M)
Capable of responding to speeds up to 1200 S.P.M (strokes/minute), suitable for both conventional and high-speed stamping presses.
3. Automatic Average Calculation
When starting operation, the machine will automatically take the measured values of the first 4 strokes to calculate the average height (Average) as the standard.
4. Channel Options
The product line offers options: SD-401 (1 channel) and SD-402 (2 channels), allowing for the protection of multiple points on the same die.
🚨Intelligent Error Alarm System
When a problem is detected, the DUCIS SD-40x will immediately stop the machine and display a clear error code:
- •SP (Speed): Abnormal press speed, machine stop, or the proximity element has fallen/is loose.
- •OP (Open Line): Broken wire, open sensor circuit, or the connector is loose/unplugged.
- •HI (High): Over-height error (slug detected). The stripper plate is lifted, distance exceeds 1.2mm.
- •LO (Low): Over-low error (die damage). The stripper plate is lower than normal, distance is below 0.8mm.
- •ES (Error): Error from external sensors (if installed) such as material end, material jam, etc.
